Hello,

lecturio.de is a platform that provides online video tutorials for very specified exams. I'd like to watch them offline in train, so I'd love to rip them.

But I'm failing.

There is a free example video, which you can access, if you register with your mailadress: https://www.lecturio.de/medizin/muendliche-pruefung-hammerexamen/spannende-praesentationen.vortrag

rtmpsrv just fails. So I tried to find the parameters with wireshark:

rtmpdump -r rtmp://vod-rtmp.lecturio.de/elearning/1305271231-34112-c-06_NEU_langweilig_praesentieren_video-v1-700.mp4 -o test.mp4 -s https://www.lecturio.de/js/jwplayer/jwplayer.flash.swf --swfhash 1bdb1ccaad412da831aecdb3b36bba8d18365b384820f36588 8494e18e525edc --swfsize 396979

Rtmpdump just fails with

INFO: Connected...
ERROR: Closing connection: NetStream.Failed

Any ideas?

Wireshark output:

Hi MPW,

lecturio does have an offline functionality in his Apps: https://play.google.com/store/apps/details?id=de.lecturio.android&hl=en

So just use them instead ;)
